Description of Prepainted Rolled steel Coil for Construction Roofing
Prepainted Rolled steel Coil is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. Aluminum zinc coils enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.
Main Feature of Prepainted Rolled steel Coil for Construction Roofing
1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside.
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover.
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials.
4. Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.
Applications of Prepainted Rolled steel Coil for Construction Roofing
1. Construction and building: roofing; ventilating duct; handrail; partition panel;etc.
2. Electric appliance: refrigerator; washing machine; refrigerator; DVD;etc.
3.Transportation: oil tank; road sign; etc.
4.Agriculture:barn; etc.
5.Others:vending machine; game machine; etc.

- Q: I heard on some shows that you can carbonise steel by heating it red hot then dropping it in black oil. i cant find this no where online, and the process for commercial carbon steel is totally different. can you really carbonise regular steel by heating it to red hot then dropping it in regular black oil. i saw it on mythbusters once. when the made carbon steel hammers to test if 2 hammers smashed together will shatter
- Carburized steel is not the same thing as carbon steel. All steel has carbon in it, but carbon steel is defined as Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 1.04 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60. Carburizing is a surface treatment. Dropping hot steel in oil is oil quenching. It might get a little carbon in the surface, but oil quenching is mainly used as a slightly slower quenching process than water quenching, not for carburizing. Once it starts cooling down the carbon won't diffuse in. Quenching is used to change the hardness. The simplest way to carburize steel is to pack charcoal around it and heat it to 900 C or so. Industrial processes use a gas like carbon monoxide, but that's mostly just for easier process control.
- Q: hello friends, I have some old 7.62x54r on stripper clips its nasty gunk on it can i use steel wool to glean it and still have it fire safely?
- * Yes, but I use both fine steel wool and Liquid Brasso Metal Polish on mine.* You can buy it at any Hardware and I believe Walmart carries it.* Great stuff.*
- Q: How are steel coils inspected for surface cleanliness using cleanliness tests?
- Steel coils are inspected for surface cleanliness using cleanliness tests through various methods such as visual inspections, magnetic particle inspections, and solvent extraction tests. Visual inspections involve visually examining the surface of the steel coils for any visible contaminants or defects. Magnetic particle inspections use magnetic particles that are applied to the surface of the coils, and if there are any defects or contaminants present, the particles will accumulate and make them visible. Solvent extraction tests involve using a solvent to extract any contaminants from the surface of the steel coils, and then analyzing the extracted solution to determine the level of cleanliness. These tests help ensure that the steel coils meet the required standards for surface cleanliness.
- Q: How are steel coils inspected for surface defects?
- Steel coils are inspected for surface defects using various methods such as visual inspection, magnetic particle testing, eddy current testing, and ultrasonic testing. These techniques help identify any imperfections or flaws on the surface of the steel coils, ensuring they meet quality standards before they are further processed or shipped to customers.

- Q: and what are the four main elements in STAINLESS steel? x
- decreasing the carbon content fabric will strengthen the ductility, which will make it greater versatile. Carbon in metallic varieties brittle cementite (iron carbide) which will strengthen the hardness and capability of metallic.
- Q: How are steel coils protected from humidity?
- Steel coils are typically protected from humidity through a process called galvanization, where a layer of zinc or another protective coating is applied to the surface of the steel. This coating acts as a barrier, preventing moisture from coming into direct contact with the steel and minimizing the risk of corrosion. Additionally, steel coils are often stored in dry, enclosed spaces or wrapped with moisture-resistant materials such as plastic or wax paper to further protect them from humidity.
- Q: I know that it is used for katanas and swords but what is it and is it good i am pretty sure that it is the process of the steel but can I have a little more information.
- Damascus or Wootz was a type of steel that appeared around 300BC It originated in India before spreading throughout Asia and the Middle East. It was considered a good steel, and for it's date of origin, exceptionally advanced for the level of technology in the ancient world. However the techniques to create the steel were lost forever after a decline in the swords manufacturing. The most popular theory is that the metal containing the required trace elements became less available over time due to unreliable trade routes. In the modern area, many scientists and metallurgists have studied the surviving blades, resulting in many discoveries such as evidence of carbon molecules fused in a crystalline structure. While the blades do provide some clues, it's only a small part of a much bigger picture as to the full process of the metal from raw to finished product. Now many have claimed to have recreated Damascus/Wootz steel, but none are recognised as being authentic. It has become a market ploy these days that draws people to purchasing the blades but all you are actually seeing is one of the many various forms of folded or patterned steel, which has varying degrees of quality, strength etc. We do know the steel was folded similar to the way the Japanese did in creation of old Katana, so often people will sell Damascus steel Katana that are nothing but folded steel swords like others. (Which is beautiful and traditional, but was a process designed to uniform impurities in the metal, something we no longer need to do with modern metals)
